mxpe works great in other countries when traveling.

Me and my wife are down visiting her family in the Dominican republic and we are on the orange network where my T-Mobile notes and s5 used to never have coverage. I have full signal strength and great coverage. This phone having all the USA carrier bands makes it easily compatible abroad. If you have loved ones in the Caribbean..get them this phone.. Ordering my wife's phone as soon as we get back.. Anyone want to buy a T-Mobile note 4?

Im from America and used it in London for five days with no real issues other than going way over my international data allowance Haha. I used WiFi when it was available at bars and my hotel and didn't have too much of a problem connecting to a network when WiFi wasn't available. Once or twice I had to wait a few minutes to connect to the Uber app but nothing I would really complain about.

The day after I received my MXPE I left for Amsterdam & Munich, Germany. Had no issues with data (Vodafone), but couldn't make/receive calls or text. Didn't bother me since I was using Messenger for calls and video chat.
